Pakto is a mobile app for signing contracts with cryptographic protection, identity verification via Diia, and legal validity under Ukrainian law.
Two big upgrades to evidentiary strength: technically verified photos and multi-party signing.
Every photo you attach now passes many independent checks at the moment of capture — proving it's a real camera frame, not AI-generated or a forgery. Each shot is hardware-signed and independently verifiable.
A single document can now be signed by several people in one ceremony. A coordinator holds the original and signs as an equal — up to 10 participants, fully offline, no server.
Business mode for companies — both for working with remote staff and freelancers, and for internal processes: handing over assets, shift handovers, administrative acts, and more. Your brand lives in every employee’s app, and every signed contract arrives in your dashboard automatically — encrypted so only you can read it.
Employees see your company name right inside the app: “PAKTO” becomes “PAKTO × [your company]”. One brand on every signature.
Every contract signed under your company’s corporate code lands in your dashboard instantly — nothing to forward by hand.
Each contract is encrypted on the employee’s device with your public key; only your private key can decrypt it — locally, in your browser. Pakto stores ciphertext only and has no access to the content.
Your private key stays with you · Decryption is local-only
From install to a signed agreement — six simple steps
Each signature is generated by a hardware key in the device's Secure Enclave. It is impossible to forge or extract the key from the device.
Both parties link a real phone number via Telegram or link an email address via a confirmation code. The SHA-256 hash of the phone number or email is permanently recorded in the document.
The signing time is synchronized with atomic clocks via TSA:zeitstempel.dfn.de according to the RFC 3161 standard. Backdating is impossible.
Sign via a link or a nearby QR code. Works without internet — data synchronizes upon the next connection.
Attach photos of the property or goods directly to the contract. The SHA-256 hash of each image is embedded in the signature and cannot be replaced.
Long-term validation under the PAdES-T standard keeps the signature cryptographically verifiable indefinitely, even after certificates expire.

Pakto provides an advanced electronic signature (AES) under the eIDAS Regulation (Art. 26) and Art. 17-1 of Law of Ukraine No. 2155-VIII. The legal force of agreements is based on the consent of the parties under Art. 207(3) of the Civil Code of Ukraine.
